The report claims Apple held the meetings to learn more about each company's development of next-generation display technologies MicroLED and MiniLED, suitable for future generations of iPhones and Apple Watches. As those names suggest, both technologies utilize arrays of very tiny LEDs.

In May, AU Optronics received a Best in Show award at the Display Week 2018 convention in Los Angeles for its multiple advanced display technologies, including the "world's highest resolution and full color TFT driven 8-inch micro LED display technology," according to the company's press release.

Apple is said to be most interested in MicroLED, as MiniLED is described as more of a transitionary technology that it may skip.

MicroLED displays have many of the same advantages as OLED displays have over LCDs, including improved color accuracy, improved contrast ratio, faster response times, and true blacks given both have self-lit pixels, but they are even thinner, much brighter, and more energy efficient than OLED panels.

MiniLED displays also have benefits such as improved brightness and contrast ratio, but they have a backlight like LCDs.
